Abstract
|
|
|
|
Humans do not have tails; however, a congenital anomaly named “human tail” has been recognized since old times. In contrast with its impactful name, the anomaly itself is not fatal, and thus it has not been considered as a clinically serious symptom. However, many case reports suggested that retention of “the tail” is closely associated with spinal cord malformation and should be treated with care by neurosurgeons. Therefore, this review summarizes our knowledge regarding the anatomy, function, and development of the tail as a general structure in mammals. Learning the basic knowledge regarding tail anatomy and development would help clinicians to understand the “human tail” more concisely and to select more appropriate examinations or treatments in relation to this congenital anomaly.
